(LiveHacking.Com) – In the wake of the new iPhone 5 announcement, Apple has released iTunes 10.7 for Windows 7, Vista and XP to include support for iOS 6 and the new iPhone plus it has taken the opportunity to update the built-in WebKit based web browser. The iTunes Store is web powered and as such uses WebKit to display the current songs, movies and TV which Apple are offering.

WebKit is an open source HTML rendering engine which Apple created. It is also used in Google Chrome. As a result when Apple or Google fix a security issue in WebKit everyone benefits, even iTunes users! This update fixes 163 vulnerabilities.

Apple explains these 163 vulnerabilities in the succinct statement: “Visiting a maliciously crafted website may lead to an unexpected application termination or arbitrary code execution.” Which it explains is due to “multiple memory corruption issues existed in WebKit. These issues are addressed through improved memory handling.”

Many of these vulnerabilities have been previously fixed in Google’s Chrome web browser with many of the vulnerabilities being credited to the “Google Chrome Security Team” or to security researchers who receive rewards from Google for finding bugs like Miaubiz. However Apple did do its fair share of the work with at least 25 of the vulnerabilities being discovered by Apple itself.

iOS 6 will become available on Wednesday, Sept. 19. It will be available for the new iPhone 5 and fifth-generation iPod Touch plus users of the iPhone 4S, iPhone 4, iPhone 3GS, new iPad, iPad 2, and fourth-generation iPod touch will be able to upgrade for free.
